2-11. Y-FM Deviation (Hi8)
: This adjustment sets the Y_FM modulation
level in recording. For adjustment, playback
the self-recorded signal and observe the
VIDEO OUT signal.
Note : It is a little difficult to adjust because you
can check the waveform in playback mode
even though the adjustment is performed
in VCR record mode.
So you have to do it carefully.
